Hi Yu Meng, About your draft I have some questions, In the "The model of combining ALTO service with relay service" part | |3.1 Integrating relay service into alto service | Are the relays provided by the application? So the ALTO sever should know the relay lists of every application ,in your model ? In the model ,should the ALTO server need to know the topology information of other ISPs? | |3.2. Cooperation between P2P application provider and ISP | | We define another model which is compatible with the current ALTO | architecture. The relay service is not integrated but considered as | the ordinary peer selection process. The peer would provide the ALTO | server with the relay candidate list, and the ALTO server would rank | the list. | Is there always only one relay between the endpoints? if not ，how to guarant that the best relay in the first step is the best in all? Thanks, FanHua
